    Characterization and morphology of thermoplastic interpenetrating polymer networks based on polystyrene and polystyrene-polyisoprene three-block copolymers (1982)

    Notes: Semi-interpenetrating polymer networks based on polystyrene and polystyrene-polyisoprene three-block copolymers (SIS) were prepared by anionic polymerization. Factors affecting synthesis, such as composition, molecular weight of either the unattached SIS or the polystyrene between crosslinks, elastomer content, have been varied. Their effect on network formation was examined by extraction experiments and swelling measurements. Their morphology was investigated by means of electron microscopy.

    Copolymérisation anionique du styrène et du divinylbenzène en présence d'une charge polymère. Influence de la masse moléculaire du polystyrène précurseur et de la nature de la charge sur la formation du gel (1985)

    Notes: Polystyrene networks, blended with various polystyrene-polyisoprene triblock copolymers, were prepared by anionic block copolymerization of styrene and divinylbenzene, the molar masses between crosslinks ranging from 5000 to 60000 g/mol. The influence of the linear polymer upon the formation of the host network was investigated by solvent extraction analysis and swelling experiments. It was found that removal of the soluble polymer out of the gel is completed within ten days of continuous extraction. The initial rate of desorption increases with decreasing the meshes of the network and with increasing the diene content of the block copolymer, i.e. the degree of incompatibility between the polymeric filler and the network. The equilibrium swelling degree of the remaining gels, completely freed of linear chains, was compared to the one of homologous model networks and revealed that the tri-dimensional structure formed in the presence of a polymer has more defects than the one prepared in pure solvent.

    Influence of a metallic filler on polyurethane formation (1996)

    Notes: The addition of metallic fillers is recognized to impart improvement of acoustic properties to polyurethane-based materials used for marine applications. The system under consideration was obtained by the reaction of a triisocyanateterminated prepolymer with 1,4-butanediol, in the presence of various concentrations of lead powder. With increasing lead content, gelation time is reduced and an Einstein-type law does not apply. The kinetics of the reaction were determined by Fourier transform infrared spectroscopy. Deviation from the classic second order is observed for the filled systems, and the higher the lead content, the more important the deviation is, showing undoubtedly the catalytic effect of the metallic powder.

    Morphology development during the polymerization of styrene within a polyurethane network: Investigations by small-angle X-ray and light scattering (1996)

    Notes: Phase separation that takes place during the formation of semi-interpenetrating polymer networks based on crosslinked polyurethane and linear polystyrene was studied by small-angle X-ray scattering and light scattering. The kinetics of the chemical reactions was followed by Fourier transform infrared spectroscopy. The occurrence of broad peaks in the X-ray scattering curves was interpreted in terms of distances between the urethane crosslinks. Small modulations on these curves were assigned to sphere-like structures with a diameter of around 5 nm which might be related to the urethane crosslink regions. Small modulations on the light-scattering curves at the beginning of styrene polymerization were assigned to spheres with diameters of around 4.5 μm, which can be related to the polystyrene-rich phase. These modulations disappear with time, which might indicate an increasing polydispersity of the domain sizes. The final morphology was found to depend on the time at which polymerization of styrene is initiated with respect to the time of gelation of polyurethane.
